18 Claims.

This invention relates generally to mountings and refers more particularly to an improved means for mounting upon a supporting Vehicle an apparatus having means for distributing material, such as sand, gravel, dirt, chloride, stone chips or other granular or loose material, over a predetermined surface such as the surface of a highway, road or street.

Usually apparatus of this type is carried at the rear end of a tiltable body of a dump truck and the material to be distributed is transferred to the hopper or receiver of the apparatus from the body of the truck when said body is tilted. Heretofore the apparatus was constructed and connected to the tiltable body in such a way that it would tilt also when the body was tilted unless it was adjusted by hand to a horizontal position. Thus, if the drive for the sand distributor or spreader of the apparatus was not cut oii when the body was tilted, the sand was thrown upwardly at an angle and oftentimes when this occurred in trafiic, bystanders were injured or property was damaged. Therefore, one of the important objects of the present invention is to provide a mounting that will enable an apparatus of the type mentioned to be carried at all times in a low, substantially horizontal or level position so that the road material may be distributed close to the ground without being thrown upwardly at an angle into trafiic.

Another object is to provide a mounting that is sturdy in construction, economical to manufacture, and easy to apply to a supporting vehicle.

Another object is to provide a mounting that may be applied to high or low or large or small trucks as desired.

Another object is to provide a mounting wherein suitable portions, such as U-shaped brackets at opposite sides thereof, serve as a gravity hitch for the sanding apparatus and are preferabl. adjustable vertically to position the apparatus at the elevation desired relative to the ground.

Another object is to provide a mounting wherein a portion thereof, such as a spreader rod, is adjustable relative to the hopper of the sanding apparatus so that said rod will serve as an abutment for the hopper regardless of the elevation thereof relative to the ground and thereby will prevent the distributing wheel or spinner of the apparatus from striking against and being damaged by the drawbar or other part of the truck or supporting vehicle when, for example, the latter is stopped suddenly while traveling on a road.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:

Figure 1 is a perspective view of the mounting per se;

Figure 2 is a side elevation of the sanding apparatus, mounting and supporting truck, with parts of the latter broken away;

Figure 3 is a fragmentary top plan view of the structure shown in Figure 2 with parts broken away;

Figure 4 is a sectional view taken substantially on the line 4-4 of Figure 1;

Figure 5 is a sectional view taken substantially on the line 55 of Figure 2.

Referring now to the drawing, A is the body of a dump truck, B is a sanding apparatus, and C is a mounting embodying my invention for supportin' the sanding apparatus upon the rear wall IQ of the truck body.

As shown, the mounting C comprises two laterally spaced upright frames I! and I2, respectively, body engaging hooks l3 and I4, U-shaped gravity hitch brackets l5 and 15, respectively, and upper and lower spreader rods l1 and I8.

The frames H and I2 are alike and each is preferably formed from angle irons and has suitable diagonal braces !8 and 20, respectively. Such frames may be any shape desired but prefera-bly each has a pair of substantially parallel uprights 2i 22, the rear uprights 22 being shorter than the front uprights 2|, and has inclined end bars 23 and 24 extending between and rigid with the uprights Z! and 22. If desired, the end bars 23 and. 24 may be integral with the rear uprights 22 or may be formed separately and terminally secured thereto. Likewise, the front uprights 2| may be integral with or formed separately from and terminally secured to the end bars 23 and 24. The braces l9 and 28 may be any suitable construction and are rigid with the front uprights 2! and end bars 23 and 2 2.

The body engaging hooks l3 and M are inverted L-shaped members and are rigid with the frames l! and i2 at their upper ends. Preferably the hooks have plate-like portions 25 disposed in sur'face-to-surface relation upon and welded or otherwise fixed to the inner sides of said frames and are provided in spaced substantially parallel relation to the adjacent front uprights 2| with depending arm portions 26. In this connection it will be noted that the plate-like portions 25 project forwardly beyond the uprights 2| and have aligned holes therein that receive the supporting ends of the upper spreader rod l1. Nuts 21 engage the supporting ends of said rod I1 upon the outer sides of the plates 25 and hold the parts together. Thus, the hooks l3 and i4 engage the upper edge of the rear wall of the dump body and the upper spreader rod I! is above and substantially in vertical alignment with said wall when the mounting is in place on the rear end of the truck.

The U-shaped gravity hitch brackets I5 and I6 are alike and each preferably consists of a U-bolt 28, nuts 29, and 3|, respectively, and a tubular sleeve 32 for the lower arm of the U-bolt. Preferably these brackets are carried by and adjustable vertically of the rear uprights 22 and project laterally inward therefrom. To permit the adjustment just mentioned, the rear uprights 22 have vertically spaced substantially horizontally aligned holes 33 therein for receiving the arms of the U-bolts 28. Thus, with this construc tion the brackets l5 and I6 may be raised or lowered depending upon the elevation desired for the distributor Wheel or spinner 34 of the sanding apparatus relative to the ground. In this connection it is desirable to have the distributing wheel 34 of the apparatus as close as possible to the ground and to have such wheel as well as the hopper 35 in a constant position relative to the ground, hence the tubular sleeves 32 of the brackets serve as pivot bearings for suitable supporting hooks 36 of the sanding apparatus and thereby permit the apparatus to always assume by gravity a vertical position regardless of whether the body A of the dump truck is tilted or not. For example, it is customary to tilt the dump body A so sand or other loose road material may slide or fall from a suitable discharge opening (not shown) in the rear wall ID of the body into the hopper 35 of the sanding apparatus. With my construction, the gravity hitch provided between the supporting hooks 36 of the sanding apparatus and the tubular sleeves 32 of the U-bolt brackets I5 and I6 is such that the sanding apparatus will remain upright in a true vertical position and thus will be unaffected when the body A of the dump truck is tilted as aforesaid.

' The lower spreader rod I8 extends between the front uprights 21 of the frames I! and I2 and is preferably adjustable vertically thereon so as to serve as an abutment or stop for the hopper 35 of the sanding apparatus and thereby. prevent the distributing wheel or spinner 34 of the apparatus from striking against and being damaged by the drawbar (not shown) or other rearward projection of the dump truck when the latter is stopped suddenly while traveling on a road. Preferably the front uprights 2! have vertically spaced substantially horizontally aligned holes 31 therein for receiving the supporting ends of the lowermost spreader rod l8 to accomplish the adjustment just mentioned.

The upper and lower spreader rods I! and I8 may be any suitable construction. For example, each may be one solid piece of metal having reduced threaded ends for insertion through suitable holes in the plates 25 and front uprights 2!, respectively, and engageable by the nuts 2'! and 38, respectively, or each may consist of a long bolt extending through the plates 25 and uprights 2|, nuts thereon at the outer sides of said frames, and tubular sleeves upon the bolts between the frames.

In use, the mounting C may be supported upon the body A of the truck by simply slipping the hooks l3 and I4 over the upper edge of the rear wall I!) of said body. Likewise, the sanding apparatus B may be supported from the mounting by slipping the hooks 36 of said apparatus over the sleeves 32 on the lower arms of the U-bolts 28 after the latter have been adjusted vertically to the desired position on the rear uprights 22. The lower spreader bar I8 is, of course, adjusted vertically on the front uprights 2| in proportion to the adjustment of the brackets l5 and [6 on the rear uprights so as to be in position as an abutment for the hopper 35 when the sanding apparatus is placed upon the mounting as aforesaid. The construction and operation of the sanding apparatus other than that set forth above is outside the present invention relating to the mounting, therefore such features have been embodied in a separate application. Any loose material may be carried by the apparatus B supported by the mounting C upon the dump truck or other suitable vehicle.
